Check your operating limitations.
It all depends on your operating limitations. If it has the latest version, then you just need to make a logbook entry, new weight & balance and place the aircraft back into Phase I for a minimum of 5 hours. You must notify the local FSDO of your proposed test area and get their concurrence. If you operating limitations are very old, you may have to get a recurrent certification.
